Virtual Adviser's™ opinion
Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the large family car segment and utilize the same 4-door sedan body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp engine designed by Volkswagen.
SafetyBoth vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, when it comes to weight, a factor that most people underestimate, Audi A4 offers a marginal difference of 1% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel, as well as Audi, with the same average rating of 4.2 out of 5. Some independent research have also placed Insignia as average reliability-wise, and A4 is more or less at the same level.That apart, owners of different cars powered by the same engine as Insignia rank it on average as 3.8, while the one under the competitor's bonnet gets 1.0 out of 5.
Performance & Fuel economyAudi is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 208 kilometers per hour, 16km/h more than the other car. When it comes to fuel economy the winner has to be Audi A4, averaging around 6.5 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 14% difference compared to Insignia.
Verdict
Opel is apparently more reliable, not too much, but just enough. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Audi A4 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Audi being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
